I worked at Skywest prior to coming to Netjets. It's a good regional job, but you need to decided what you want to do with your career.
Neither job offers everything Netjets is asking for. At OO you will build time quicker, have a more stable job, but won't get your ATP for at least 2-3 years if you wait till you upgrade.
The King Air job will get you your ATP but take 5-6 years to build the time needed for NJ. Plus, as others have mentioned, until the plane is on the ramp and your type is in your pocket, there is no job.
If you are willing to move to an OO domicile, I would say go there. Money will be tight, but it's doable. Get yourself on a tight budget and start saving for that ATP at All ATPs. Get your time and certificate and get your resume in.
If you live in domicile, QOL won't be bad. Commuting sucks and will make your live miserable.
Good luck.
